足月婴儿和早产儿在一个或多个场合受到单一和重复的闪光刺激。从枕叶皮层（头皮）记录的反应与成人的不同之处在于波形更多变，振幅更多变（通常更高），潜伏期更长，疲劳性更强。随着年龄增长的发育变化已经得到证实;其中最显著的是：（a）从一些受试者最早记录中的初始负相反应转变为初始正相的经典反应;（B）反应潜伏期缩短;（c）对越来越快的重复刺激反应的能力增强。反应潜伏期也与体重呈负相关。反应潜伏期与年龄和反应潜伏期与体重的曲线是两条腿，而不是单调的，可能反映了不同的发展速度在两个部分（暗视和明视？）的视觉系统。所描述的人类数据在大多数方面与猫和兔报告的数据相似。人类婴儿的视觉系统在出生时似乎比猫和兔子的视觉系统在生理上更成熟，但猫和兔子在出生后发育得更快。人类的个体差异和其他两个物种的个体差异一样显著。
Full-term and premature babies have been stimulated on one or more occasions by single and repetitive flashes of light. The responses recorded from the occipital cortex (scalp) differ from those of adults in being of more variable wave-form, more variable (and often higher) amplitude, longer latency, and greater "fatigability." Developmental changes with increasing age have been demonstrated; the most notable of these are (a) change from a response with initial negative phase in the earliest records of some subjects to the classical response with initial positive phase, (b) decreasing response latency, and (c) increasing ability to respond to more and more rapidly repeated stimuli. Response latency is also inversely correlated with body weight. Curves of response latency vs age and of response latency vs body weight are 2-legged rather than monotonic, perhaps reflecting different developmental rates in the two parts (scotopic and photopic?) of the visual system. The human data described are in most respects similar to those reported for cats and rabbits. The visual system of the human infant appears to be physiologically more mature at birth than that of the cat and the rabbit, but the latter develop more rapidly postnatally. Individual differences are as striking in the human as they are in the other two species.
